Peter Capaldi has started to worry about getting older since becoming a grandfather

He told the Guardian newspaper: "I'm a grandparent now so suddenly I have babies and lullabies in my life again. It's wonderful, but being Scottish there's always a melancholic streak in me that will seek out the bleak thing about it.

"In this case it's the ticking clock. These fabulous children bring all this vigour and chaos into your life, but how long do you have left to spend with them.

"That made me think of the entropy of the universe and how awful the world is. And how just about the only moment I have any control over is putting the bins out."

Peter channelled his feelings into a song called 'Bin Night' which features on his second album 'Sweet Illusions'.

He added of the track: "I don't know if it's the only song ever written about bin night but it's a great subject."

He went on to say: "A lot of the songs deal with ageing. Wondering where all the time has gone. 'Big Guy' is about those people who were once full of braggadocio and swagger but are now dribbling on their jumpers. We remember them as something else now."

Peter - who released his first album 'St. Christopher' in 2021 - is adamant he doesn't worry about how his music is received because he's primarily an actor.

He explained: "I wasn't nervous of putting this music out. It doesn't matter. It's not my profession ...

"My songs were originally more something I was doing for myself. I thought, OK, if I am going to have a go at making music it has to be music I want to make. I'm not going to do a Peter Capaldi Christmas album."
